-' 3.Claims. (Cl. 161-39) This invention relates to a diaper washing composition. n An object of the present invention is to provide a washing composition tor baby diapers that will both clean and fluff the diapers. c V

' Another object of the present invention is to provide a washing composition for baby diapers that will prevent diaper rash and related discomtorts. Furthermore, introduction of the present invention will serve to eliminate already existing diaper rash and irritation.

Still another object of the present invention is to provide a Washing composition for baby diapers, which will kill certain bacterial organisms in the diapers that cause diaper rash.

A hurther object of the present invention is to provide a washing composition for baby diapers which will kill other bacterial organisms in the diapers that cause odors.

An additional object of the present invention is to provide a washing composition for baby diapers which makes the diapers more absorbent than before washing and thus remain drier and correspondingly reduces tation in use.

Still another object of the present invention is to provide a washing composition for baby diapers which makes the diapers very same to cause irritation when used.

Further purposes and uses of the present invention are the cleansing and deodorizing of clothing, bed-sheets, blankets from sick beds and sanitizing toys, walls, floors, carpets, rugs, mattresses, and in fact all forms of cloth, leather, plastic, metal or glass objects.

To make 100 lbs. or approximately 220 kilograms of the composition, the dollowing procedure is herewith detailed and has been found to be critical: In one container dissolve in water 100 grams of the stilbene derivative known as HS-76 in 102.5 liters of water.

soft, thereby reducing the tendency of United States Patent 3,101,297 Patented Aug. 20, 1963' the Du iont Company. It contains material of, a fattynature. The constituency is N,N,N',N' tetrakis (2-hydroxy prcpyl) diamino diol eate methosulphate. The tune;

tion of this ingredient in the washing composition is a flufiing agent, a detergent, an anti-bacterial and antistatic agent. It further makes the diapers more water absorbent.

8.8 kilograms of tetrapotassium' pyrophosphate 4 2 'i' 2 in 46.25 litersof water. The tunction at in the composition is as a'water softener and cleansing 1 agent. Then add this solution to the contents oi the In a third container, dissolve 3 grams of any suitable coloring agent in 8.8 liters [of water. Sevron Blue, a commercial product made by the Du Pont Company, hasbeen hound quite suitable for the desired purpose. The hunction of this ingredient is to impart a pleasing color to the composition. This solution is now added to the contents of the first container. 7 I

While continuing vigorous agitation of the solution, 100 grams lOf any suitable pertume is added. The perfume known as Delicate Bouquet No. 26,529, made by Fritzsche Brothers, has been found to be quite desirable. The purpose of this ingredient is to impart a pleasing odor to the composition.

The final step in the preparation-of the composition 7 is the addition of 17.6 kilograms of an n-alkyl dimethyl activity. Ihis ingredient functions as the quaternary This is a commercial product available from the Antara cunt-Ow omens OH-n=9V This is a commercial product manufactured Chemicals, Inc. It is a non-ionic detergent. tion of this ingredient in the composition is to act as a wetting, emulsifying, and dispersing agent, and, of course, a detergent.

At the same time add 7.7 kilograms of Aerotex Purifying Agent No. 1. This is a commercial product manufactured by American Cyanamid Company. It contains certain cationic material materials which stabilize neomycin sulphate.

The exact [formula .of this chemical composition is not known but it is believed to contain 1.6% of neomycin sulphate and the probable tormula is C H N O S-O The tunction of this ingredient in the composition is turther to reduce odors, particularly ammonia odors, and to kill bacteria.

by Onyx The tun'ci of the diaper material is preserved and accordingly the component of the composition."

As previously stated, the above procedure been hound to be critical with the exception that the, times of mixing the ingredients are not important. The only requirement here is that they should be thoroughly mixeduntil all of the ingredients are in solution. I

The above described procedure will result in a sparkling clear solution. While the [foregoing preparation has, through experimentation, been found to producethe best possible end product, deviations of up to 30% in the amounts of the several ingredients will still result in a workable diaper washing composition.

In use the composition is added to the waterin which the diapers are to be washed in the amount of 4 teaspoons to the gallon. When diapers are washed in water containing the composition according to the invention, ammonia forming and odor producing bacteria are eliminated from same. Also, the new finish and iiufiy nature common causes of diaper rash are eliminated.

The above specification is to be taken as illustrative of the inventive concept thereof, and is not meant to be limiting, the invention being limited only by the scope of the appended claims.

I claim:
